W3/230 Water Vapor Transmission Rate Test System

Product catalog summary
Overview
The W3/230 Water Vapor Transmission Rate Test System by Labthink Instruments Co., Ltd. is a professional, high-efficiency, and intelligent system designed to measure the water vapor transmission rate (WVTR) of films and packages. It features three test modes suitable for materials with varying water vapor permeability and is equipped with a high-precision infrared sensor.

Specifications
The system offers a wide test range from 0.1 to 1000 g/m²·24h and supports non-standard test conditions with precise temperature and humidity control. It can test three specimens simultaneously, providing independent results for each.

High Efficiency
The W3/230 system uses an infrared sensor method and integrates three diffusion cells in one instrument, enhancing test efficiency by three times. It includes an embedded computer control system for reliable data management and operation, and features multiple connectivity options for data transmission.

Intelligent Features
The system includes user-friendly software with intelligent data management, supporting the Lystem™ Lab Data Sharing System for uniform test result management. It offers intelligent designs for test evaluation, sensor calibration reminders, and operation record management.

Test Principle
The system uses the infrared method, where the specimen is placed in a diffusion cell divided into dry and controlled-humidity chambers. Dry nitrogen carries the water vapor permeating through the specimen to the infrared sensor, where electrical signals are generated and analyzed to determine the WVTR.

Standards and Applications
The instrument conforms to ISO 15106-2, ASTM F1249, TAPPI T557, and JIS K7129 standards. It is applicable to a wide range of materials, including films, sheeting, paper, packages, and extended applications like package caps, LCD monitor films, solar back-sheets, and more.

Technical Specifications
The system supports a test range of 0.01 to 40 g/m²·24h for films and 0.0001 to 0.2 g/pkg·d for packages. It accommodates specimens up to 108 mm x 108 mm and thicknesses up to 3 mm. The temperature range is 15°C to 55°C with an accuracy of ±0.1°C, and humidity ranges from 0%RH to 100%RH with an accuracy of ±1%RH.

Configurations
Standard configurations include the mainframe, software, LCD monitor, keyboard, mouse, and other accessories. Optional parts are available for packaging tests and additional functionalities.

Note
Labthink reserves the right to change technical specifications without notice. Customers are advised to check the website for the latest updates.

W3/230 Water Vapor Transmission Rate Test System-2

Infrared method is used by W3/230 Water Vapor Transmission Rate Test System: The test specimen is mounted in the diffusion cell, which is subsequently divided into a dry chamber and a controlled-humidity chamber. The dry side of the specimen is swept by a flow of dry nitrogen, and the water vapor permeating through the specimen from the controlled-humidity chamber is carried by dry nitrogen to the infrared sensor where proportion electrical signals will be generated. The water vapor transmission rate is obtained by analyzing and calculating the electrical signals. For package samples, dry nitrogen...
